I'm hoping you guys can help me out here. I've been trying different methods to try and get what IW as hoping would be a fairly simple script but has turned into a pain.
Bit of background - I am writing a script to check values in certain failes to ensure they are corerct. I'm runnign this on a Citrix Netscaler which is based on FreeBSD.
The problem I'm having is passing the output of a command into a variable.
currect script thats failing:
Code:
CVer="9,2,45,7"
RunningStore="/netscaler/ns_gui"
rFServicesCVer=$ cat $RunningStore/vpns/f_services.html | grep "var clientversion"
if [ $rFServicesCVer = "var clientversion=$CVer" ]
then
echo $runningpath/f_services.html contains the correct value
else
echo $runningpath/f_services.html contains the incorrect value
fi
When I run this script the $rFServicesCVer does not appear to get set
tested this by putting an echo before the if and I got the following output
Code:
if [ = var clientversion=9,2,45,7
if I echo the variable above as a test that the variable is set and I get nothing.
what is strange is when the script runs and the $rFServicesCVer is edclaired it seems to run the command and output the correct value so it's as if it's running the command rather then setting it as a variable.
any help much appreciated - if what I've written doesnt make sense let me know as I may not have explained it very well.
Hi Stuc(k), welcome to the forum. For starters, try these modifications:
Code:
CVer="9,2,45,7"
RunningStore="/netscaler/ns_gui"
rFServicesCVer=$(cat "$RunningStore/vpns/f_services.html" | grep "var clientversion")
if [ "$rFServicesCVer" = "var clientversion=$CVer" ]
then
echo $runningpath/f_services.html contains the correct value
else
echo $runningpath/f_services.html contains the incorrect value
fi
Many thanks Scrutinizer that brackets have done the job! I'm now getting the variable set as expected.
I am for some reason getting "[: too many arguments" when I do the IF command though for some strange reason
Code:
CVer='"9,2,45,7"'
VPNNum="vpn9"
PersistentPath="/var/vpn/custom/"
RunningStore="/netscaler/ns_gui"
rFServicesCVer=$(cat $RunningStore/vpns/f_services.html | grep "var clientversion")
if [ $rFServicesCVer = "var clientversion=$CVer" ]
then
echo $runningpath/f_services.html contains the correct value
fi
I'm not sure I understand how the second suggestion you gave works

sorry - realised I hadnt quoted the first variable in the IF like you said and thats why I got that error.
